    One of the best Buying-Experiences I’ve ever made! A high quality product with very strong firepower. After one screw was missing, maybe because the border-police opened it, frontline foam helped me very quick and send me 4 new srews. I can just recommend this kit, cause it lets u also a lot of space for your one improvements. And, by the way, Frontline Foam offers also very good ones. I personally buys the acetal Plunger and an improved ramrod. 5/5!

    10/10. I’m just getting into nerf, and I’ve seen plenty of videos of the Caliburn. Since I have a printer at home, I decided to buy the hardware kit. Frontline Foam’s Caliburn assembly video is very descriptive, and the one problem we had with the blaster was with one of the parts I designed. It shoots wonderfully and is practically too powerful for me to use inside the house. So strong, in fact, that I lost most of my darts or the tips came off. Great customer service. I would strongly recommend this hardware kit to anyone who has a 3d printer at home and is looking for a high-power blaster.
